D | memory-allocation.rst | 19 Linux为内存分配提供了多种API。你可以使用 `kmalloc` 或 `kmem_cache_alloc` 109 分配内存的最直接的方法是使用kmalloc()系列的函数。而且,为了安全起见,最好使用将内存 114 可以用 `kmalloc` 分配的块的最大尺寸是有限的。实际的限制取决于硬件和内核配置,但是对于 115 小于页面大小的对象,使用 `kmalloc` 是一个好的做法。 117 用 `kmalloc` 分配的块的地址至少要对齐到ARCH_KMALLOC_MINALIGN字节。对于2的幂的大小, 120 用kmalloc()分配的块可以用krealloc()调整大小。与kmalloc_array()类似:以krealloc_array() 126 如果你不确定分配的大小对 `kmalloc` 来说是否太大,可以使用kvmalloc()及其派生函数。它将尝 127 试用kmalloc分配内存,如果分配失败,将用 `vmalloc` 重新尝试。对于哪些GFP标志可以与 `kvmalloc` 136 当分配的内存不再需要时,它必须被释放。你可以使用kvfree()来处理用 `kmalloc` 、 `vmalloc`
